ABSTRACT:
The disclosed methods of low power communications facilitate high speed reception of data from an access point (AP) with low transmission latencies while remaining in power save mode as long as possible. The disclosed methods allow the client to remain in a power save state and involve creating a synchronous client frame exchange with the AP that is independent of a digital traffic indication map and the AP's beacon interval. Two methods to accomplish this goal are disclosed: one which involves sending PS Poll Frames; and one that includes fast CAM switching, both at a self tuning frequency.
